W6 Full Coverage vs W8 Slim Specs
suction power
The FMART W6 offers 3800Pa of suction power, which the manufacturer states adjusts automatically to handle light or heavy dirt. This variable suction helps protect glass while removing stubborn stains. In contrast, the FMART W8 provides 8000Pa of suction. This higher force allows the W8 to grip glass more firmly and resist wind. The W8 also adjusts real-time pressure to match surfaces. If you need maximum holding strength for large or windy windows, the W8’s stronger suction is the clear choice. The W6’s lower power is still effective for standard cleaning tasks.
build
Dimensions matter when you have tight spaces. The W6 measures 9.6 inches wide, 9.6 inches long, and 3.4 inches high. It is a standard rectangular shape. The W8 is significantly smaller and thinner. It measures 8.3 inches wide, 8.3 inches long, and only 2.4 inches high. The W8 is described as ultra-slim and portable. It is 30% thinner and 26% smaller than typical models. This slim profile allows it to reach railing windows, small frames, and tilting windows that the larger W6 cannot access. If your windows have narrow frames or tight corners, the W8’s compact build is superior.
navigation type
The W6 uses SLAM technology for navigation. It relies on advanced mapping and multiple sensors to detect window frames, edges, and obstacles. This allows it to map efficient paths and adapt to frameless glass. The W8 also uses precision sensors for edge cleaning. It stops spray near frames and changes direction smartly. However, the data does not explicitly state if the W8 uses SLAM mapping or a different navigation method. The W6’s specific mention of SLAM suggests more structured path planning. If you prefer predictable, mapped cleaning routes, the W6’s navigation technology is the stronger option.
control method
Both robots support app and remote control. The W6 includes a dedicated 2.4G remote with a 10-meter range and through-wall operation. It also offers an APP with voice control and troubleshooting guides. The W8 supports App Control and Remote Control as well. It allows you to switch between four cleaning modes with one tap. The W8’s app control enables deep cleaning, edge scrubbing, and spot removal. While both offer versatile control, the W6’s remote has specific interference resistance and through-wall features. The W8 offers more distinct cleaning modes via its interface. Both are easy to operate for different needs.
special features
The W6 features a dual water tank design with a water-saving system. It uses ultrasonic sprays to turn water into a fine mist, reducing streaks. It also has a UPS system providing 30 minutes of operation during power outages. The W8 uses four ultrasonic nozzles for wide-angle spraying. It has a 95ml tank and a backup battery that provides 50 minutes of emergency suction. The W8 also includes self-cleaning brushes and floating suction cups to absorb shocks. The W8’s longer emergency battery life and self-cleaning brushes are notable advantages. The W6’s dual tanks may reduce refill frequency for larger jobs.
Choose the right FMART for you
Users with large, frameless glass panes
The W6 uses SLAM navigation and AI path planning to map your entire window surface. Its 99.73% coverage rate and wide 9.6-inch footprint ensure it reaches corners effectively. The variable 3800Pa suction adapts to dirt levels, while the dual water tanks reduce refill frequency during extensive cleaning sessions.
Those needing access to tight spaces
The W8 is only 2.4 inches thick, making it 30% thinner than the W6. This slim profile allows it to fit into small windows, railings, and tight spots where larger robots cannot go. Its compact 8.3-inch size also helps it maneuver in constrained areas without getting stuck.
People prioritizing maximum suction power
The W8 delivers 8000Pa of suction, which is more than double the W6's 3800Pa. This higher force helps resist wind and grips glass securely on high floors. The real-time pressure adjustment ensures consistent cleaning performance even in challenging environmental conditions, providing strong adhesion and dust removal.

Frequently asked questions
Which robot is better for windows with railings?
The FMART W8 Ultra-Slim is the better choice for windows with railings. Its slim profile allows it to fit into tight spaces that bulkier units cannot reach. The W6 is wider and may not clear obstacles like railings effectively.
How wide is the FMART W6 robot?
The FMART W6 measures 9.6 inches in width and length. This wider footprint helps it cover more surface area in a single pass. It is designed for standard windows where maximum coverage is the priority over navigating tight gaps.
Does the W8 robot support remote control?
Yes, the FMART W8 supports both app control and remote control. This dual method gives you flexibility in how you operate the device. You can use the remote for quick adjustments or the app for more detailed navigation settings.
What is the thickness of the W8 model?
The FMART W8 has a height of 2.4 inches. This ultra-slim design is key to its ability to clean narrow windows. It sits lower than the W6, making it ideal for frames with limited clearance.
Can the W6 robot clean corners effectively?
The FMART W6 is designed for full-coverage cleaning on standard windows. Its 9.6-inch width and SLAM navigation help it map the entire surface. This approach ensures it reaches corners and edges consistently without missing spots during its cleaning cycle.
Is the W8 robot suitable for large panes?
The W8 is primarily built for tight and railing windows. While it cleans effectively, its smaller 8.3-inch size means it covers less area per pass than the W6. For very large, frameless panes, the W6 might be more efficient.
What color options are available for these models?
Both the FMART W6 and W8 are available in white. The W6 is listed as W6-white and the W8 as W8-white. The color choice does not affect the cleaning performance or the specific features of each model.
